It struggles to get and hold a high temperature.  The oil drain system is fantastic. I suspect the couple reviews that said it leaked is due to the lid of the oil reservoir not on securely. When you unscrew the drain plug make sure the top piece is securely snapped into place to the base of the oil reserve. When that occurs there is zero leakage.  It slides out and into the refrigerator without issue. Other than the high temperature hold I would have given the unit 5 stars.  There is an obvious knock off to this product with black plastic handles versus the metal ones. I’m glad I went with the real product the construction is excellent.
